If you own a legacy Mac with OS X Leopard 10.5.8 and earlier, you can no longer run Skype, the Microsoft-owned company has confirmed today.

Following a string of complaints from disgruntled users who took to the Skype forum last week reporting they were being locked out from accessing the VoIP service, a Skype team member penned a note confirming that the program was no longer supported on Macs running OS X Leopard 10.5.8 and older.

People running Skype on OS X 10.6 Snow Leopard, 10.7 Lion and 10.8 Mountain Lion are unaffected so “there is no need to upgrade to Mavericks or Yosemite if you don’t want to” reads the message…

Skype staff member wrote the following in response to the issue:

There seems to be a lot of confusion around this. First, let me assure you that no-one is locking you out from using Skype on OS X 10.6 – 10.8 and there is no need to upgrade to Mavericks or (the new OS X now in dev preview) Yosemite if you don’t want to.

The free of charge iPhone and iPad edition of Skype currently lets you initiate a one-to-one video call and participate in audio-only group calls, but you can’t start a group voice or video call. And while you can join a group video call on your iPhone and iPad, you’ll be downgraded to audio only.

Phillip Snalune, Skype’s General Manager of Consumer Product Marketing, confirmed to The Next Web that Windows Metro, Windows Phone, Android and iOS platforms will soon support free group video calling.

According to Skype’s FAQ, other unsupported features on iOS include synchronizing with iOS Contacts, showing favorite contacts and screen sharing (you can’t share your screen with your contacts, but they can share their screen with you during a one-to-one video call).
